I am using gdb to examine a core file but the output contains only the method addresses in hex.
Is there anyway to translate these addresses to a human-readable form? :confused: (0 Replies)

I am trying to print a stack trace programatically using backtrace and backtrace_symbols.
The problem is that the stack being printed in a mangled format. Is there a way to get the output in more of a human readable form?

Hi all,
I was hoping someone can point me in the right direction. I'm trying to filter out errors from a web log- any lines with ERROR in it. I know I could simply use the grep command to do this. However, there are times when a stack trace follows the error line. I would like to capture these... (2 Replies)

Hi all,
One of our programs written in Java, produced this logfile. This job runs 48 threads and only one thread failed with this error.

Hi All
Thought it would be kind of fun to implement a stack trace for a shell script that calls functions within a sub shell. This is for bash under Linux and probably not portable -

sgglse.f
sgglse.f(3) LAPACK sgglse.f(3)
NAME
sgglse.f -
SYNOPSIS
Functions/Subroutines
subroutine sgglse (M, N, P, A, LDA, B, LDB, C, D, X, WORK, LWORK, INFO)
SGGLSE solves overdetermined or underdetermined systems for OTHER matrices
Function/Subroutine Documentation
subroutine sgglse (integerM, integerN, integerP, real, dimension( lda, * )A, integerLDA, real, dimension( ldb, * )B, integerLDB, real,
dimension( * )C, real, dimension( * )D, real, dimension( * )X, real, dimension( * )WORK, integerLWORK, integerINFO)
SGGLSE solves overdetermined or underdetermined systems for OTHER matrices
Purpose:
SGGLSE solves the linear equality-constrained least squares (LSE)
problem:
minimize || c - A*x ||_2 subject to B*x = d
where A is an M-by-N matrix, B is a P-by-N matrix, c is a given
M-vector, and d is a given P-vector. It is assumed that
P <= N <= M+P, and
rank(B) = P and rank( (A) ) = N.
( (B) )
These conditions ensure that the LSE problem has a unique solution,
which is obtained using a generalized RQ factorization of the
matrices (B, A) given by
B = (0 R)*Q, A = Z*T*Q.
Parameters:
M
M is INTEGER
The number of rows of the matrix A. M >= 0.
N
N is INTEGER
The number of columns of the matrices A and B. N >= 0.
P
P is INTEGER
The number of rows of the matrix B. 0 <= P <= N <= M+P.
A
A is REAL array, dimension (LDA,N)
On entry, the M-by-N matrix A.
On exit, the elements on and above the diagonal of the array
contain the min(M,N)-by-N upper trapezoidal matrix T.
LDA
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
B
B is REAL array, dimension (LDB,N)
On entry, the P-by-N matrix B.
On exit, the upper triangle of the subarray B(1:P,N-P+1:N)
contains the P-by-P upper triangular matrix R.
LDB
LDB is INTEGER
The leading dimension of the array B. LDB >= max(1,P).
C
C is REAL array, dimension (M)
On entry, C contains the right hand side vector for the
least squares part of the LSE problem.
On exit, the residual sum of squares for the solution
is given by the sum of squares of elements N-P+1 to M of
vector C.
D
D is REAL array, dimension (P)
On entry, D contains the right hand side vector for the
constrained equation.
On exit, D is destroyed.
X
X is REAL array, dimension (N)
On exit, X is the solution of the LSE problem.
WORK
WORK is REAL array, dimension (MAX(1,LWORK))
On exit, if INFO = 0, WORK(1) returns the optimal LWORK.
LWORK
LWORK is INTEGER
The dimension of the array WORK. LWORK >= max(1,M+N+P).
For optimum performance LWORK >= P+min(M,N)+max(M,N)*NB,
where NB is an upper bound for the optimal blocksizes for
SGEQRF, SGERQF, SORMQR and SORMRQ.
If LWORK = -1, then a workspace query is assumed; the routine
only calculates the optimal size of the WORK array, returns
this value as the first entry of the WORK array, and no error
message related to LWORK is issued by XERBLA.
INFO
INFO is INTEGER
= 0: successful exit.
< 0: if INFO = -i, the i-th argument had an illegal value.
= 1: the upper triangular factor R associated with B in the
generalized RQ factorization of the pair (B, A) is
singular, so that rank(B) < P; the least squares
solution could not be computed.
= 2: the (N-P) by (N-P) part of the upper trapezoidal factor
T associated with A in the generalized RQ factorization
of the pair (B, A) is singular, so that
rank( (A) ) < N; the least squares solution could not
( (B) )
be computed.
